背景技术Background technique
为了满足广大用户的使用需求，可以针对不同的电子设备设置多种不同的内存配置。以电子设备是手机为例，同一款手机既可以设置2G内存配置，即总内存容量为2GB＝2048MB(兆字节)；也可以设置3G内存配置，即总内存容量为3GB＝3072MB(兆字节)，在实现的过程中，可以基于内存分配器来进行内存的分配。In order to meet the needs of users, a variety of different memory configurations can be set for different electronic devices. Taking the electronic device as a mobile phone as an example, the same mobile phone can be set to a 2G memory configuration, that is, the total memory capacity is 2GB=2048MB (megabytes); it can also be set to a 3G memory configuration, that is, the total memory capacity is 3GB=3072MB (megabytes). Section), in the process of implementation, memory allocation can be performed based on the memory allocator.
相关技术中，内存分配器能够实现多线程并发，且为了提升多线程并发分配的性能，设置了线程局部缓存功能，以减少多线程之间的同步所导致的性能损耗，但是，线程局部缓存功能会使得内存的消耗增加。由于相关技术中在编译过程中就决定了是否开启线程局部缓存功能，无法针对不同的电子设备进行差异化配置，且如果在编译期间就确定了缓存策略，在电子设备使用的过程中无法动态调整缓存策略。In the related art, the memory allocator can realize multi-thread concurrency, and in order to improve the performance of multi-thread concurrent allocation, the thread local cache function is set to reduce the performance loss caused by synchronization between multiple threads. However, the thread local cache function Will increase memory consumption. In the related art, it is determined during the compilation process whether to enable the thread local cache function, so it is impossible to perform differential configuration for different electronic devices, and if the cache strategy is determined during compilation, it cannot be dynamically adjusted during the use of electronic devices. caching strategy.

本公开实施例中提供了一种缓存处理方法，该方法可以应用于电子设备。图1是根据一示例性实施例示出的缓存处理的流程示意图一，如图1所示，该方法主要包括以下步骤：An embodiment of the present disclosure provides a cache processing method, which can be applied to an electronic device. FIG. 1 is a schematic flow chart 1 of cache processing according to an exemplary embodiment. As shown in FIG. 1 , the method mainly includes the following steps:
在步骤101中，获取所述电子设备的当前内存状态；In
在步骤102中，根据与所述当前内存状态对应的缓存策略，确定是否开启应用程序进程的线程局部缓存功能。In
本公开实施例中所涉及的缓存处理方法可以应用于电子设备，这里，电子设备包括终端设备，如移动终端和固定终端，其中，移动终端包括：手机、平板电脑、笔记本电脑等；固定终端包括：个人计算机。在其他可选的实施例中，该缓存处理方法也可以适用行于配置安卓(Android)操作系统的嵌入式电子设备。The cache processing method involved in the embodiments of the present disclosure can be applied to electronic devices, where the electronic devices include terminal devices, such as mobile terminals and fixed terminals, wherein the mobile terminals include: mobile phones, tablet computers, notebook computers, etc.; fixed terminals include :Personal computer. In other optional embodiments, the cache processing method may also be applicable to embedded electronic devices configured with an Android (Android) operating system.
这里，当前内存状态可以包括：电子设备在开启过程中的内存状态，以及电子设备开启成功后的内存状态。在获取到电子设备的当前内存状态后，能够确定与该当前内存状态对应的缓存策略，并根据该缓存策略确定是否开启应用程序进程的线程局部缓存功能。Here, the current memory state may include: the memory state of the electronic device during the booting process, and the memory state after the electronic device is successfully powered on. After acquiring the current memory state of the electronic device, a cache policy corresponding to the current memory state can be determined, and whether to enable the thread local cache function of the application process is determined according to the cache policy.
在一些实施例中，该电子设备具有设定类型的操作系统，针对该操作系统，可以设置对应的内存分配器，且该内存分配器配置有线程局部缓存功能。例如，如果该设定类型的操作系统为Android操作系统，则可以使用Jemalloc作为内存分配器，对应的，该内存分配器配置有线程局部缓存功能。其中，线程局部缓存功能是针对各个应用程序进程中的各个线程设置的，在实现的过程中，如果开启了线程局部缓存功能，则可以针对各个线程配置对应的线程局部缓存区域，并基于该局部缓存区域存储各个线程的对象。In some embodiments, the electronic device has an operating system of a set type, and for the operating system, a corresponding memory allocator can be set, and the memory allocator is configured with a thread local cache function. For example, if the operating system of the set type is the Android operating system, Jemalloc can be used as the memory allocator, and correspondingly, the memory allocator is configured with a thread local cache function. Among them, the thread local cache function is set for each thread in each application process. During the implementation process, if the thread local cache function is enabled, the corresponding thread local cache area can be configured for each thread. The cache area stores objects for individual threads.
以电子设备是具有Android操作系统的电子设备为例，由于Jemalloc具有优秀的多线程并发分配性能，Android操作系统可以使用Jemalloc作为内存分配器。由于持续开启线程局部缓存功能会使得电子设备的内存消耗增加，在实现的过程中，可以获取电子设备的当前内存状态，并根据当前内存状态对应的缓存策略，确定是否开启应用程序进程的线程局部缓存功能。Taking an electronic device having an Android operating system as an example, since Jemalloc has excellent multi-threaded concurrent allocation performance, the Android operating system can use Jemalloc as a memory allocator. Since the continuous opening of the thread local cache function will increase the memory consumption of the electronic device, during the implementation process, the current memory state of the electronic device can be obtained, and according to the cache policy corresponding to the current memory state, it is determined whether to open the thread local of the application process. cache function.
例如，可以获取电子设备的总内存，在电子设备的总内存大于或者等于第一设定内存的情况下，开启电子设备中所有应用程序进程的线程局部缓存功能。再例如，可以在电子设备的总内存小于第一设定内存的情况下，关闭电子设备中所有应用程序进程的线程局部缓存功能。For example, the total memory of the electronic device may be acquired, and the thread local cache function of all application processes in the electronic device is enabled when the total memory of the electronic device is greater than or equal to the first set memory. For another example, when the total memory of the electronic device is less than the first set memory, the thread local caching function of all application processes in the electronic device may be disabled.
本公开实施例中，可以通过获取电子设备的当前内存状态，并根据与当前内存状态对应的缓存策略，确定是否开启应用程序进程的线程局部缓存功能。相较于相关技术中在编译期间就确定缓存策略，并按照该固定的缓存策略开启或者关闭应用程序进程的线程局部缓存功能，本公开实施例中，能够根据电子设备的内存状态灵活调整缓存策略，即根据电子设备的内存状态开启或者关闭应用程序进程的线程局部缓存功能，能够实现缓存策略的动态调整。In the embodiment of the present disclosure, it can be determined whether to enable the thread local cache function of the application process by acquiring the current memory state of the electronic device and according to the cache policy corresponding to the current memory state. Compared with the related art in which the cache policy is determined during compilation, and the thread local cache function of the application process is enabled or disabled according to the fixed cache policy, in the embodiment of the present disclosure, the cache policy can be flexibly adjusted according to the memory state of the electronic device. , that is, according to the memory state of the electronic device, the thread local caching function of the application process is turned on or off, so that the dynamic adjustment of the caching strategy can be realized.
在一些实施例中，所述获取所述电子设备的当前内存状态，包括：In some embodiments, the acquiring the current memory state of the electronic device includes:
在检测到开启所述电子设备的开启指令时，获取所述电子设备的总内存；Obtaining the total memory of the electronic device when detecting an opening instruction to turn on the electronic device;
所述根据与所述当前内存状态对应的缓存策略，确定是否开启应用程序进程的线程局部缓存功能，包括：The determining whether to enable the thread local cache function of the application process according to the cache policy corresponding to the current memory state includes:
在所述总内存大于或者等于第一设定内存的情况下，开启所述电子设备中所有所述应用程序进程的线程局部缓存功能。In the case that the total memory is greater than or equal to the first set memory, the thread local caching function of all the application processes in the electronic device is enabled.
这里，开启指令可以是用户基于电子设备上的控件触发的指令，其中，控件可以是虚拟控件，也可以是物理按键。本公开实施例中，电子设备在检测到该开启指令的时候，可以启动该电子设备，并在启动该电子设备时获取电子设备的总内存。Here, the opening instruction may be an instruction triggered by a user based on a control on the electronic device, where the control may be a virtual control or a physical button. In the embodiment of the present disclosure, when the electronic device detects the start-up instruction, the electronic device can be activated, and the total memory of the electronic device can be acquired when the electronic device is activated.
例如，可以通过电子设备开机的过程中启动的第一个进程读取电子设备的总内存。再例如，可以在电子设备开机的过程中，基于init()函数读取电子设备的总内存。For example, the total memory of the electronic device can be read through the first process started during the process of turning on the electronic device. For another example, the total memory of the electronic device may be read based on the init( ) function during the booting process of the electronic device.
在获取到电子设备的总内存之后，可以将电子设备的总内存与第一设定内存进行比较，得到第一比较结果，并根据第一比较结果确定是否开启电子设备中的应用程序进程的线程局部缓存功能。After the total memory of the electronic device is obtained, the total memory of the electronic device can be compared with the first set memory to obtain a first comparison result, and according to the first comparison result, it is determined whether to open the thread of the application process in the electronic device Local cache function.
例如，在第一比较结果表征电子设备的总内存大于或者等于第一设定内存的情况下，开启电子设备中所有应用程序进程的线程局部缓存功能。由于开启局部缓存功能会消耗电子设备的内存，本公开实施例中，在电子设备的总内存充足的情况下，开启所有应用程序进程的线程局部缓存功能，能够在保证电子设备的可用内存充足的基础上，保证应用程序进行的运行速度。For example, when the first comparison result indicates that the total memory of the electronic device is greater than or equal to the first set memory, the thread local caching function of all application processes in the electronic device is enabled. Since enabling the local cache function will consume the memory of the electronic device, in the embodiment of the present disclosure, when the total memory of the electronic device is sufficient, enabling the thread local cache function of all application processes can ensure that the available memory of the electronic device is sufficient. On the basis, the running speed of the application is guaranteed.
在另一些实施例中，在电子设备的总内存大于或者等于第一设定内存的情况下，可以开启电子设备中部分应用程序进程的线程局部缓存功能。例如，在电子设备的总内存大于或者等于第一设定内存的情况下，可以开启电子设备中的N个应用程序进程的线程局部缓存功能，其中，N可以根据需要设定，例如，可以是3或者5等，在此不做具体限定。In other embodiments, when the total memory of the electronic device is greater than or equal to the first set memory, the thread-local caching function of some application processes in the electronic device may be enabled. For example, when the total memory of the electronic device is greater than or equal to the first set memory, the thread local caching function of N application processes in the electronic device can be enabled, where N can be set as required, for example, it can be 3 or 5, etc., are not specifically limited here.

Jemalloc为了提升多线程并发分配性能使用了线程局部缓存功能，以避免多线程间同步导致的性能损耗，但是开启线程局部缓存功能会使得内存消耗增加。相关技术中，线程局部缓存功能是默认开启的，例如，Jemalloc默认在编译期间就选择了开启或关闭线程局部缓存功能，比如，可以在低内存配置的电子设备上选择关闭线程局部缓存功能以节省内存消耗。相关技术中，Jemalloc在编译脚本中定义了决定是否开启线程局部缓存功能的宏变量，Jemalloc在初始化代码中根据是否设置宏变量决定是否开启线程局部缓存功能，在实现的过程中，需要修改编译脚本来实现打开或关闭线程局部缓存功能的目的。Jemalloc uses the thread-local cache function to improve the concurrent allocation performance of multiple threads to avoid performance loss caused by synchronization between multiple threads, but enabling the thread-local cache function will increase memory consumption. In the related art, the thread local cache function is enabled by default. For example, Jemalloc chooses to enable or disable the thread local cache function by default during compilation. For example, the thread local cache function can be disabled on electronic devices with low memory configurations to save memory consumption. In the related art, Jemalloc defines a macro variable in the compilation script to determine whether to enable the thread local cache function. Jemalloc determines whether to enable the thread local cache function according to whether the macro variable is set in the initialization code. During the implementation process, the compilation script needs to be modified. To achieve the purpose of opening or closing the thread local cache function.
电子设备产品一般存在多个内存配置，比如同一款手机可以具有2G、3G或者4G的内存，在实现的过程中，具有2G和3G内存配置的手机需要关闭线程局部缓存功能以节省内存，而具有4G内存配置的手机则可以开启线程局部缓存功能获得更好的性能。Jemalloc默认在编译期间就选择了开启或关闭线程局部缓存功能，无法在具有不同内存的同一款电子设备上进行差异化配置。Electronic equipment products generally have multiple memory configurations. For example, the same mobile phone can have 2G, 3G or 4G of memory. During the implementation process, the mobile phone with 2G and 3G memory configurations needs to turn off the thread local cache function to save memory. Mobile phones with 4G memory configuration can turn on the thread local cache function for better performance. Jemalloc chooses to enable or disable the thread local cache function by default during compilation, and cannot be configured differently on the same electronic device with different memory.
且在Android操作系统中，Jemalloc无法根据电子设备在使用过程中的内存压力动态调整缓存策略，比如在内存压力大的时候对新启动的进程关闭线程局部缓存功能，在内存压力小的时候对新启动的进程开启线程局部缓存功能。And in the Android operating system, Jemalloc cannot dynamically adjust the caching strategy according to the memory pressure of the electronic device during use. The started process enables thread-local caching.
在一些实施例中，本公开实施例中的技术方案由Jemalloc，libc，Framework三个部分组成。在实现的过程中，可以修改内存分配器的用于控制线程局部缓存功能的全局变量的配置函数，由运行时只读修改为运行时可读可写。例如，可以修改Jemalloc的config模块中控制线程局部缓存功能的全局变量opt_tcache的配置函数，由运行时只读修改为运行时可读可写，并在libc的mallopt函数中新增参数选项OPT_TCACHE，用于在单线程情况下修改Jemalloc的全局变量opt_tcache，以便关闭或开启线程局部缓存功能。In some embodiments, the technical solutions in the embodiments of the present disclosure consist of three parts: Jemalloc, libc, and Framework. In the implementation process, the configuration function of the global variable of the memory allocator for controlling the thread local cache function can be modified from read-only at runtime to readable and writable at runtime. For example, you can modify the configuration function of the global variable opt_tcache that controls the thread-local cache function in the config module of Jemalloc, from read-only at runtime to readable and writable at runtime, and add the parameter option OPT_TCACHE to the mallopt function of libc, using Modify the global variable opt_tcache of Jemalloc in the case of a single thread to turn off or turn on the thread local cache function.
图2是根据一示例性实施例示出的缓存处理的流程示意图二，如图2所示，该方法主要包括以下步骤：Fig. 2 is a second schematic flowchart of cache processing according to an exemplary embodiment. As shown in Fig. 2, the method mainly includes the following steps:
在步骤201中，读取电子设备的总内存。In
这里，可以通过电子设备开机的过程中启动的第一个进程读取电子设备的总内存。再例如，可以在电子设备开机的过程中，基于init()函数读取电子设备的总内存。Here, the total memory of the electronic device can be read through the first process started during the process of starting the electronic device. For another example, the total memory of the electronic device may be read based on the init( ) function during the booting process of the electronic device.
在步骤202中，确定电子设备的总内存是否小于第一设定内存。In
这里，可以根据电子设备的总内存决定打开或关闭线程局部缓存功能。例如，在获取到电子设备的总内存之后，可以将电子设备的总内存与第一设定内存进行比较，得到第一比较结果，并根据第一比较结果确定是否开启电子设备中的应用程序进程的线程局部缓存功能。比如，在总内存小于第一设定内存的情况下，关闭电子设备中所有应用程序进程的线程局部缓存功能。Here, the thread local cache function can be turned on or off according to the total memory of the electronic device. For example, after obtaining the total memory of the electronic device, the total memory of the electronic device can be compared with the first set memory to obtain a first comparison result, and according to the first comparison result, it is determined whether to start the application process in the electronic device Thread-local caching capabilities. For example, when the total memory is less than the first set memory, the thread local caching function of all application processes in the electronic device is disabled.
在步骤203中，如果总内存小于第一设定内存，则设置属性ro.boot.disable_tcache为true。In
这里，如果需要关闭线程局部缓存功能，可以设置属性ro.boot.disable_tcache为true。Here, if you need to turn off the thread local cache function, you can set the property ro.boot.disable_tcache to true.
在步骤204中，init进程fork(派生)子进程。In
在步骤205中，确定init进程fork出的子进程读取到的ro.boot.disable_tcache属性是否为true。In
在步骤206中，如果子进程读取到的ro.boot.disable_tcache属性为true，则将环境变量JEMALLOC_DISABLE_TCACHE设置为1。In
这里，在后续的开机过程中，如果init进程fork出的子进程读取到ro.boot.disable_tcache属性为true，则可以将环境变量JEMALLOC_DISABLE_TCACHE设置为1。Here, in the subsequent boot process, if the child process of the init process fork reads that the ro.boot.disable_tcache attribute is true, the environment variable JEMALLOC_DISABLE_TCACHE can be set to 1.
在步骤207中，如果子进程读取到的ro.boot.disable_tcache属性不为true，则子进程使用exec系统调用执行新的可执行文件时，libc会重新初始化。In
在步骤208中，确定环境变量JEMALLOC_DISABLE_TCACHE是否为1。In
这里，可以在libc初始化的过程中读取JEMALLOC_DISABLE_TCACHE环境变量，并确定环境变量JEMALLOC_DISABLE_TCACHE是否为1。Here, you can read the JEMALLOC_DISABLE_TCACHE environment variable during libc initialization, and determine whether the environment variable JEMALLOC_DISABLE_TCACHE is 1.
在步骤209中，如果JEMALLOC_DISABLE_TCACHE环境变量存在且值为1，则直接将决定线程局部缓存是否打开的全局变量opt_tcache设置为false，以关闭线程局部缓存功能。In
在一些实施例中，由于Android应用程序(Application，App)是通过zygote进程fork出来的，而zygote是通过init进程fork出来的，因此我们只要在电子设备(例如，手机)启动过程中将zygote进程的线程局部缓存功能关闭，后续所有应用程序进程的线程局部缓存都会被关闭。In some embodiments, since the Android application (Application, App) is forked through the zygote process, and the zygote is forked through the init process, we only need to fork the zygote process during the startup process of the electronic device (eg, mobile phone). The thread-local cache function of the application process is turned off, and the thread-local cache of all subsequent application processes will be turned off.
图3是根据一示例性实施例示出的缓存处理的流程示意图三，如图3所示，该方法主要包括以下步骤：FIG. 3 is a schematic diagram 3 of a cache processing flow according to an exemplary embodiment. As shown in FIG. 3 , the method mainly includes the following steps:
在步骤301中，请求zygote进程启动新应用程序进程。In
在步骤302中，基于zygote进程fork子进程。In
在步骤303中，确定电子设备的当前可用内存是否小于或者等于第二设定内存。In
在步骤304中，在电子设备的当前可用内存小于或者等于第二设定内存时，使用新增的mallopt选项OPT_TCACHE将决定线程局部缓存是否打开的全局变量opt_tcache设置为false，以关闭线程局部缓存功能。In
这里，以电子设备是手机为例，在手机使用过程中，可以根据手机整体内存状态决定是否打开或关闭新启动的应用程序进程的线程局部缓存功能。比如，当前整体内存状态较差，则可以将新启动的应用程序进程的线程局部缓存功能关闭，以节省内存。Here, taking the electronic device as a mobile phone as an example, during the use of the mobile phone, whether to enable or disable the thread local cache function of the newly started application process can be determined according to the overall memory state of the mobile phone. For example, if the current overall memory state is poor, the thread local caching function of the newly started application process can be turned off to save memory.
在一些实施例中，在zygote进程fork出的应用程序进程处于单线程状态使，可以使用新增的mallopt选项OPT_TCACHE将决定线程局部缓存是否打开的全局变量opt_tcache设置为false，以关闭线程局部缓存功能。In some embodiments, when the application process forked from the zygote process is in a single-threaded state, the new mallopt option OPT_TCACHE can be used to set the global variable opt_tcache that determines whether the thread local cache is enabled to false to disable the thread local cache function .
在一些实施例中，可以在电子设备的开启过程中，根据电子设备的整体内存状态调整缓存策略。还是以电子设备是手机为例，如某款手机存在3G，4G内存两种配置，且两种内存配置的手机烧录的是相同的软件包，在实现的过程中，可以通过修改Jemalloc底层函数，实现手机支持运行时打开或者关闭线程局部缓存功能，并在手机开机过程中判断手机实际内存大小(总内存)，并基于该实际内存大小确定是否开启线程局部缓存功能。例如，对3G手机中的所有应用程序进程关闭线程局部缓存功能，对4G手机中的所有应用程序进程打开线程局部缓存功能。In some embodiments, the cache policy may be adjusted according to the overall memory state of the electronic device during the turning-on process of the electronic device. Or take the electronic device as a mobile phone as an example. For example, a mobile phone has two configurations of 3G and 4G memory, and the mobile phones with the two memory configurations are programmed with the same software package. In the process of implementation, the underlying function of Jemalloc can be modified by , to realize that the mobile phone supports turning on or off the thread local cache function at runtime, and judges the actual memory size (total memory) of the mobile phone during the mobile phone boot process, and determines whether to enable the thread local cache function based on the actual memory size. For example, the thread local caching function is disabled for all application processes in a 3G mobile phone, and the thread local caching function is enabled for all application processes in a 4G mobile phone.
在另一些实施例中，可以在电子设备的运行过程中，根据电子设备的整体内存状态调整缓存策略。还是以电子设备是手机为例，在手机运行的过程中，可以根据手机的整体内存状态调整缓存策略，例如，可以监听手机的当前内存状态，在内存压力大的时候对新启动的应用程序进程关闭线程局部缓存功能，在内存压力小的时候对新启动的应用程序进程开启线程局部缓存功能。In other embodiments, the cache policy may be adjusted according to the overall memory state of the electronic device during the operation of the electronic device. Taking the electronic device as a mobile phone as an example, during the operation of the mobile phone, the cache strategy can be adjusted according to the overall memory status of the mobile phone. For example, the current memory status of the mobile phone can be monitored, and the newly started application process can be monitored when the memory pressure is high. Turn off the thread local cache function, and enable the thread local cache function for the newly started application process when the memory pressure is small.
通过本公开的技术方案，一方面，解决了在电子设备运行时，如何根据内存大小或者其它状态信息决定是否开启或关闭系统所有应用程序进程的线程局部缓存功能的问题。另一方面，解决了如如何根据具体策略对部分应用程序进程开启线程局部缓存功能，同时对另外一部分应用程序进程关闭线程局部缓存功能的问题。而且采用了本公开的技术方案后，实现了内存占用和分配上的均衡，2G内存配置的电子设备能够节省60-100M内存，3G内存配置的电子设备能够节省100-300M内存。The technical solution of the present disclosure, on the one hand, solves the problem of how to determine whether to enable or disable the thread local cache function of all application processes of the system according to the memory size or other state information when the electronic device is running. On the other hand, it solves the problem of how to enable the thread local cache function for some application processes according to a specific strategy, while turning off the thread local cache function for another part of the application process. Moreover, after adopting the technical solution of the present disclosure, the balance of memory occupation and allocation is realized, the electronic device with 2G memory configuration can save 60-100M memory, and the electronic device with 3G memory configuration can save 100-300M memory.
